A thin bar on the right side allows you to preview the pages or the document structure, and jump to any part of the file. You can zoom in and zoom out, jump to a particular page, move to the next or previous page and save the file to your system. Once installed, click on any PDF file link and it will open in the same tab. Whether the PDF file is being opened from your hard drive or from a link, the extension opens it in the browser, allowing you to forgo the need of having a PDF viewer installed. Pdf.js is a Firefox add-on that makes up for one such missing feature in Firefox it allows you to open PDF files in the browser as you would in Chrome. Practically any feature that you might find missing or too niche to be integrated as a full feature, can be added with the appropriate extension or script. Firefox, no doubt, is a browser that gives you a ton of flexibility with its add-ons.
